1. **State the problem:** We need to rewrite sentences by adding a comma after the words "yes" or "no" when they appear at the beginning of a sentence, capitalize the first letter, and end with the correct punctuation. 2. **Rule:** When "yes" or "no" starts a sentence, it should be followed by a comma to separate it from the rest of the sentence. 3. **Rewrite each sentence:** - Original: no the car doesn't sound quite right - Step: Capitalize "No" and add a comma after it. - Result: **No, the car doesn't sound quite right.** - Original: yes the fan belt is making a squealing noise - Step: Capitalize "Yes" and add a comma after it. - Result: **Yes, the fan belt is making a squealing noise.** - Original: no I don't need to remove the tires - Step: Capitalize "No" and add a comma after it. - Result: **No, I don't need to remove the tires.** - Original: yes I already found your car - Step: Capitalize "Yes" and add a comma after it. - Result: **Yes, I already found your car.**
